GSoC 2016 [Hovakim Grabski]

Friday, January 5, 2018

It has been a while since I have posted.
This will be a very short post.

If you plan to use GROMACS with GPU support and Anaconda Python Distribution, it is much better to install GROMACS first then Anaconda.
If you try to install GROMACS after installing Anaconda, you will receive compilation errors (Particularly GCC errors).
The easiest way to fix on Linux ( in my case Ubuntu 16.04) is to comment line of Anaconda (.bashrc file). Compile and install GROMACS with GPU support and then uncomment.
Or just install GROMACS first then Anaconda.

It's almost over

Finally after 4 months GSoC the end is near. It was a awesome experience to work with SBML and JSBML team and how much work and efforts they put in this project and what is to work in a collaboration. If it is possible I would like to continue my work after GSoC.

Repository Information

Background

Because there have been of a lot of changes since the first post, I would like to introduce Deviser's code generator to produce Java code once again.

SBML Packages

Computation modeling has become a crucial aspect of biological research, and SBML (the Systems Biology Markup Language) has become the de facto standard open format for exchanging models between software tools in systems biology.

Since SBML Level 3 is being developed as a modular format with optional SBML Level 3 packages are available to extend the focus of the core SBML representation. Deviser is a new code generation system developed to facilitate the development of SBML L3 packages by helping to automate the generation of specifications, UML diagrams and library code.

The current fork extends Deviser's code generator to produce Java code that can be integrated into JSBML, the pure Java API library for SBML. This allows Deviser to target both libSBML and JSBML. At the current stage it generates the foundation of the packages, which facilitates their implementation.

Using Deviser for Java Code Generation

There is command line version of the function that can be used to invoke the deviser functionality for generating Java/JSBML code from the XML file. This is the deviser.py file found in the generator directory.

deviser.py [--generatejsbml][--latex] input-file.xml

Requirements for the fork

Deviser requires javap for the java code generation at the current phase. Javap is available with the JDK and the following is required for Devisers' java code functionality.

Also set up JAVA_HOME environment variable for your operating system, if you are working under Windows, here is a good tutorial on how to set up. And for Linux: Ubuntu/Debian.

Current State

At the current state Deviser generates compilable templates, which serve as a foundation and facilitate the implementation of the following packages :

Qualitative Models package (qual, for short) allows species in a model to have non-quantitative or non-continuous levels. (Chaouiya et al., 2013)

Groups (groups, Hucka and Smith, 2013) agglomerates SBML model elements and can be linked to annotations and SBO terms (Courtot et al., 2011) to contextualize sets of objects for other programmers and modelers.

What is left to be implemented

Specific parts of the packages are left to be implemented.

Flux Balance Constraints (fbc, Olivier and Bergmann, 2013) encodes components for constraints based modeling (Lewis et al., 2012), which employs a class of models in which the canonical stoichiometric relations between reactions and metabolites are specified as constraints for mathematical optimization.

I would also like to optimize 'imports' parts, as well as to find an alternative to javap, which is used extensively, so deviser does not have any dependency for Java/JSBML code generation.

Java Tests

For running Java code generation tests, please head to generator/tests/test_java_code and run

run_java_tests.py

If there are any errors, it will also show the code differences.

Final Notes

So,this is the end. As I said, it was a great summer and I had a lot of fun working on this project. I could recommend everyone who wants to improve the coding skills to apply for the Google Summer of Code. There's nothing to lose, but you will gain a lot, specially invaluable knowledge and experience. And even if you are not a system biologist, it is a promising field, so checkout the projects of the SBML and JSBML team.

Acknowledgments

I am very grateful to my mentors Dr. Bergmann, Dr. Keating, Dr. Dräger and Dr. Rodriguez for the invaluable help and patience.

Important bugs were fixed in readAttributes and toString method generators.

The constructor generator was updated as well as the hashCode generator.

Tests were set up and run fine both on Windows and Linux.

A prototype README.md version was created.

Updated some parts of the code comments, but still there is work to be done.

The good news is that the parser generator was finalized and that generated code by deviser for qual, dyn,distrib and groups packages are compilable.

The plan is to spend the next 2-3 days cleaning up the code and updating the comments, since deviser is quite complicated and there are tricky moments. They are available at WIP branch of the fork repository.

One addition to the tests was creating a new function for comparing the generated files with the test units, the new function uses difflib from python and now it is possible to see the differences and the lines if there are errors.
And the good news are that the codes generated for qual, fbc, dyn, distrib and groups packages are compilable(53dd6b7).

So far from the packages only 'spatial' is left to be adapted, that means the necessary functions need to be adapted for the code generation. And there is also the question for the generation of the parser.

Still Work in Progress....

Tests

Last week a compilable class goal was achieved.So this week was about setting up tests.

Since deviser generates and select random UUID and prime number, the two methods were adapted for running tests. In the case of prime number, random.seed was set to 0 as for the UUID to a fixed number,as random seed would not affect it.

The foundation of java tests served test_cpp_code files, which were adapted for the java files generation. The path separator was changed to os.sep, so it uses OS specific separator.

javap parser

jsbml jar was put inside deviser package and javap works under Windows as well.
